Write the following equations of these parabolas in vertex form : focus at (-5,-3), and directrix y=-6
focus at (10,-4), and directrix y=6

I am having a lot of trouble with these so I would really appreciate it if someone could help. I am giving away all my points.

what golf ball

step-by-step explanation:

i think c. but don't trust it.

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
